Litz Wire

三層絶縁電線 は、スイッチング電源トランス用に

uses a Litz wire. This is a wire with three-layered insulation, which accomplished a smaller outside diameter and excellent solderability by using the special coat stranded wire developed a new though it is a low loss equivalent to a Litz wire. The wire has reinforced insulation with tape. *2

DC, Litz wire with more strands of finer wire must be used, raising R DC because increased in-sulation and voids reduce the copper area. Thus, at frequencies where core eddy current losses dominate, core loss worst case is at high VIN, full load. Winding loss worst case is always at low VIN, full load..

use the largest wire that will fit into the window. This minimizes losses, and maximizes the power rating for a transformer. High frequency windings are more complex to deal with for reasons as described below. b. Single Wire Skin Effect multi-wire and proximity effects.

Mar 17, 2020 · PAGE 30 L LK Inductance A lot of models can be found in literature for calculating the leakage inductance. Two of them are: CLASSICAL MODEL: This is a simple method for calculating the leakage inductance since only a small number of dimensions are necessary related to the winding geometry.
